It’s really no surprise that Disney is going to fold in it’s hugely popular Frozen into the crossover fantasy would of the ABC series Once Upon A Time, especially given the tease at the very end of the season finale. It’s now official, as they’ve cast their Elsa, Anna and Kristoff. Australian actress Georgina Haig, who previously appeared on Fringe, will play Elsa. Her younger sister Anna will be played by newcomer Elizabeth Lail, while Anna’s love interest Kristoff will be Scott Michael Foster (Greek, Halt and Catch Fire).

It is uncertain how many episodes the characters or the storyline will appear in, but given the seemingly insatiable appetite of Frozen fans, I’m going to predict “as long as it keeps merchandise sales going…”
